--- Comment #6 from Jean-Baptiste Mardelle <j...@kdenlive.org> --- Hi, Finally found some time to look at this issue. The problem seems to be that MLT/FFmpeg (video backend) does not provide a reliable length for some of your mp3 files. So Kdenlive detects that the file duration has changed and creates a backup. I still have to check that part in Kdenlive... are you using a recent FFmpeg version ? -- You are receiving this mail because: You are watching all bug changes.
